TC1264-2.5VEBTR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TC1264-2.5VEBTR is a fixed-output CMOS low dropout regulator providing 800 mA output current with a nominal voltage of 2.5 V. It operates within an input voltage range of 2.7 V to 6.0 V and maintains high accuracy (±0.5%). The device features very low dropout voltage, typically 450 mV at full load, and ultra-low noise operation. Supply current is typically 80 µA at full load. Integrated protections include overcurrent and overtemperature shutdown. It is stable with a minimum 1 µF output capacitor.
